WIND-WHEEL.

SPECIFICATION forming part of Letters Patent No. 426,241, dated April22, 1890.

Application filed May 22, 1889. Serial No. 311,701. (No model.)

T0 all whom it may concern:

Be it known that I, ASA W. OHAMEERLIN, of Stratford, in the coun ty ofHamilton and State of Iowa, have invented a new and useful Improvementin Wind-lVheels, of which the following is a specification.

My invention consists in a new and improved wind-wheel, which will behereinafter fully described and claimed.

Referring to the accompanying drawings, Figure 1 is aside view of my newand improved wind-wheel. Fig. 2 is a top plan view of the same. Fig. 3is a detail view of one of the fans. Fig. 4 is a detail viewillustrating one of the inner fan-stops, and Figs. 5 and 6 are detailviews hereinafter referred to. l

The same numerals of reference indicate corresponding parts in all thefigures.

Referring to the several parts by their designating-numerals, 1indicates the vertical shaft, which is revolved by the wind-wheel, beingsupported in suitable bearings in a frame 2. The upper end of this shafthas the arms 3 projecting at right angles to it, and on these arms aremounted the fans 4. These fans are arranged in vertical planes, half ofeach fan being above and half below its arm 3. Each fan consists of anupper and lower half connected. at their rear edge and secured togetherby a rod 5, leaving an open space between the halves of the fan, so thatit can turn eompletel y around in its bearings on the wheel-arm, ashereinafter set forth. The fans are secured on each arm parallel to eachother on the same side of the arm by bearingplates 6, stops 7 on therods 5 preventing the upper half of the fan from bearing on the up perpart of the arm.

Then the fans are closed, the free front edge of each fan bears againstrearward projections 8 of the fan in front of it, these rear projectionsof the fans serving to hold the fans closed when the wind is blowingagainst them. The fans are all thus held or braced, except the innermostfan on each arm, which is held shut against a hinged stop 9, consistingof a rod 10, having parallel stop-plates 11 11 at each end. This rod 10is supported in a bearing-plate 12 at the rear of the arm 3, as shown,and a projection 13 on the rod holds the upper stop-plate 11 up clear ofthe arm. Vhen the stop 9 is turned so that the outer edge of theinnermost fan lrests against the free ends of the stop-plates 11, thesaid fan is held or supported in its closed position with the windblowing against it, and the outer fans rest with their free outer edgesagainst the stops 8', which project, as shown, from the rear of eachfan.

It will be seen by reference to 2, in

which the direction of the wind is indicated by the small arrows, thatthe air pressing on the fans that are to the left-hand side of thecentral horizontal line 0o cc, looking in the di rection indicated bythe small arrows, will keep the said fans closed and revolve the wheelin the direction indicated by the large arrows in Fig, 2, while, as soonas the arms pass down below the line ma, the fans all opensimultaneously under the pressure of the wind and hang with their edgeto the wind, as shown in the right-hand half of Fig. 2,1ooking in thedirection of the small arrows, and when they reach and rise above theline am they are closed or locked against each other ready to receivethe pressure of the wind; but if the hinged stop 9 is drawn or turnedtoward the center of the wheel, so that it will not catch the free edgeof the inner most fan, all the fans on that arm will turn in theirbearings and hang edge to the wind, as will be readily understood, sothat no pressure will be exerted by the wind on that arm of the wheel.

For automatically regulating the speed the hinged stop 9 of each arm haspivoted to it at the points 13 one end of a rod 14, the other end ofwhich is pivotally connected to the outer part of a disk 15, which iscentrally pivoted on a bracket 1G, as shown, and from the lower part ofeach disk 15 is suspended a governor-ball 17. lt will be seen that asthe shaft 1 is revolved by the wheel the balls 17 of each arm will swingout and up, turning the plates or disks 15 with them, and when the speedreaches a certain height the governonballs will rise sufiieiently highto turn the disks 15, so that the connecting-rods 14 will draw thehinged stops 9 toward the center of the wind-wheel clear of the innerfans 4, when the fans will turn their edges to the wind and the wheelwill slow down, as no pressure can then be exerted by the wind. As thespeed falls, the governor-balls will fall lOO -will be readilyunderstood.

until the stops 9 again engage the inner fans, when the fans will againbe held shut for the wind to exert its pressure against them.

To stop the wheel or mill entirely, a tube 18 is mounted loosely on theshaft 1, being formed with a slot 19, and a pin 20,in the shaft fits inthis slot, so that the tube is held from turning around on the shaft,but can slide up and down thereon. Each disk 15 is pivotally connectedto the upper end of the tube 18 by a rod 21, the pin 22 at the upper endof each rod fitting in a curved slot 23 in that disk 15. The lower cudof the tube 18 is formed with a flange 23a, which fits and turns in acollar 24 ot' a plate 25, the plate remaining stationary while theflanged end of the tube revolves in the collar. One end of the plate 25is hinged to a bearing 26, while to the other end is secured a rod orcord 27. It will be seen that when the rod 27 is pulled down the plate25 will draw down the tube 18, which, through the rods 21, will turn thedisks 15, so as to turn the hinged stops 9 clear of the inner fans, whenthe fans will turn their edges to the wind, and the wheel will be thusstopped. The curved slots 23 in the disks 15 permit of the disks beingturned by the governor-balls 17 without moving the tube 18. It will beseen that the nearer the point of attachment of the governor-ball is tothe end of the rod 14 on its disk 15 the higher the governor-ball willhave to swing to draw the stop 9 free of the innermost fan. Therefore byputting the governor-balls of two opposite arms at the same distancefrom the rods 14 on their disks and placing the governor-balls of twoopposite arms at points fartherdown on their disks, requiring a higherrate of speed to open their fans, the wheel will be so gaged that itcannot run above a certain speed even if the work be light, as The powercan be conveyed. from the vertical revolving shaft 1 either by a belt orgear-wheels in the usual manner. The outer ends of the fan-arms areconnected by bracerods 28.

My new and improved wind-wheel is simple and strong in construction andexceedingly efficient in its operation. It dispenses with the usualvane, and the pressure of the wind is direct instead of glancing.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. In a wind-wheel, the combination, with a fan-arm, of the fansconsisting of the upper and lower halves 4 4, having the rearprojections 8, and connected by the edge rod 5, having the stop, and thestop hinged ou the arm and consisting of the rod 10, having the endplates 11 11 and the projection 13, substan tially as set forth.

2. In a windwheel, the combination, with the vertical shaft `and thefan-arms, of the fans formed with the upper and lower blades 4 4 andhaving the rear projections 8, the stops 9, having the upper and lowerplates 11 and hinged on the arms, the disks 15, centrally pivoted on thebrackets 16, the rods 14, pivotally connecting the stops 9 and the disks15, and the governor-balls 17, attached to the disks, substantially asset forth.

3. In a wind-Wheel, the combination, with the vertical shaft and thefan-arms, of the fans 4 4 5, having the rear projections 8, the stops9,hinged on the arms, the disks 15, centrally pivoted on the brackets 16and having the curved slots 23, the governor-balls 17, the slottedmovable sleeve 18, and the stop-pin 20, and the connecting-rods 14 and21, sub stantially as set forth.

4. In a wind-wheel, the combination, with the vertical shaft and thefan-arms, of the fans 4 4 5, having the rear projections 8, the stops9,hinged on the arms, the disks 15, centrally pivoted on the brackets16, the slotted movable sleeve 18, having the flange 23n at its lowerend, the connecting-rods 14 and 21, the hinged plate 25, formed with thecollar 24, and the rod 27, connected to the plate 25, substantially asset forth.
